The Hidden Costs of Owning a Car Nobody Warns You About
Most first-car budgets stop at the purchase price and insurance quote. The costs that actually catch people out — VED, MOT, servicing, depreciation — sit quietly underneath, and together they can add up to more than the car itself cost in a given year.

The Short Answer
Beyond the purchase price and insurance, budget for Vehicle Excise Duty (VED, commonly called road tax — £200 a year for most petrol, diesel and hybrid cars from year two), an annual MOT once the car turns three (capped at £54.85), regular servicing and unpredictable repairs, fuel, parking and depreciation if you ever plan to sell or part-exchange it. Together, these ongoing costs commonly add several hundred to well over a thousand pounds a year on top of insurance, depending on the car’s age, condition and how much you drive.
Vehicle Excise Duty (VED / “Road Tax”)
The standard rate. For most petrol, diesel and hybrid cars registered after April 2017, the standard annual rate from the second year of registration onward is £200 (slightly more if paid monthly by direct debit rather than annually).
First-year rates vary significantly based on the car’s emissions, ranging from very low for zero-emission vehicles up to substantially higher rates for the most polluting new vehicles — this is a one-off cost in the car’s first year of registration, typically already factored into a new car’s on-the-road price.
Electric vehicles now pay VED too — a low first-year rate, moving to the £200 standard rate from year two, following changes that ended the previous VED exemption for electric cars.
The expensive car supplement. Cars with a list price over £40,000 (petrol/diesel) or £50,000 (electric, from April 2026) pay an additional supplement on top of the standard rate for several years — relevant mainly for higher-value cars, but worth knowing if you’re considering a car near that threshold.
The MOT Test
Once a car reaches three years old, it legally requires an annual MOT test, checking roadworthiness, safety and emissions compliance. The maximum fee a garage can charge is capped at £54.85 for a standard car, though many garages charge less, particularly if bundled with a service.
What genuinely catches new car owners out isn’t the test fee itself — it’s the cost of any repairs needed to pass. A car that fails its MOT needs the identified faults fixed before it can be legally driven on the road again (with limited exceptions for driving directly to a pre-booked repair), so budgeting only for the test fee and not for potential repair costs is a common and expensive mistake.
Servicing and Repairs
Regular servicing (typically annual, or based on mileage) catches developing issues before they become expensive failures, and is also often required to maintain any remaining manufacturer warranty. Skipping services to save money in the short term is a common way small, cheap-to-fix issues develop into large, expensive ones.
Repair costs are inherently unpredictable, which is exactly why they’re easy to underbudget for — a car that’s run perfectly for a year can still develop an expensive, unplanned fault the next. Setting aside a modest ongoing amount specifically for car maintenance, rather than treating every repair as an unexpected emergency expense, makes this far more manageable.
Fuel and Charging
An easy cost to underestimate if you’re used to occasional lifts rather than regular independent driving — actual fuel costs depend heavily on how much you drive, the car’s efficiency, and current fuel prices, which fluctuate. Tracking your actual mileage and fuel spend for the first month or two of ownership gives a far more accurate ongoing budget figure than a rough guess based on the car’s advertised efficiency alone.
Parking
Depending on where you live, parking can range from free to a genuinely significant recurring cost — a residents’ permit, a workplace parking charge, or regular pay-and-display costs if you don’t have off-street parking. This is easy to overlook when budgeting for a first car if you haven’t previously needed to think about where a car would actually live day to day.
Depreciation
Cars lose value over time, and this matters even if you’re not planning to sell soon — it affects what you’d get back if your circumstances change, and it’s part of the true overall cost of ownership even though it isn’t a cash cost you pay directly each month. New cars typically depreciate fastest in their first few years, which is one reason a slightly older, already-depreciated used car can be a stronger first-car financial choice than a brand-new one.
A Realistic Annual Running Cost Checklist
- VED: roughly £200 a year for most standard petrol, diesel or hybrid cars from year two.
- MOT (once applicable): up to £54.85, plus any repair costs needed to pass.
- Servicing: varies by car, typically an annual cost worth budgeting for specifically.
- Insurance: highly variable, particularly for new drivers — see our guide on car insurance for new drivers.
- Fuel or charging: based on actual mileage and driving patterns, not a rough guess.
- Parking: check local costs before assuming this is negligible.
- A repair buffer: a modest, regular set-aside amount for unplanned issues, rather than treating every repair as a surprise.
Common Mistakes When Budgeting for Car Ownership
Budgeting only for the purchase price and insurance, treating everything else as an afterthought rather than a genuine recurring cost.
Not researching a specific car’s typical reliability and repair costs before buying, which can vary significantly even between similarly priced used cars.
Skipping services to save money short-term, which often costs more overall once a preventable issue becomes a major repair.
Forgetting parking costs entirely if moving somewhere without guaranteed off-street parking.
First Wage Takeaway
The purchase price of a car is the beginning of the cost, not the whole of it — VED, MOT, servicing, fuel and parking are all genuinely recurring costs that, added together, often rival or exceed the cost of insurance itself. Budgeting for the full annual running cost, not just the upfront price, is what actually determines whether a car is affordable.
Frequently Asked Questions
How much does it typically cost to run a car for a year, beyond insurance?
This varies enormously by car and location, but VED, an MOT (once applicable), servicing, fuel and parking together commonly add several hundred to well over a thousand pounds a year on top of insurance, depending heavily on the specific car and how much it’s driven.
Do electric cars have lower running costs overall?
Often yes for fuel/charging and servicing, though this depends on the specific vehicle, your access to home charging, and current VED rules, which have changed to include EVs rather than exempting them entirely as in previous years.
Is it worth getting an extended warranty on a used car?
It can provide useful protection against unexpected large repair costs, though it’s worth weighing the warranty’s cost and exclusions carefully against the specific car’s likely reliability before deciding.
What’s the biggest hidden cost first-time car owners usually miss?
Repair costs from failed MOTs and unplanned mechanical issues are commonly the most underbudgeted cost, since they’re unpredictable and easy to assume won’t happen until they do.
